This example demonstrates a Java utility for determining whether a character or string contains Chinese characters. The code defines a `CharacterUtils` class with two static methods: `isChinese(char)` checks a single character by comparing its Unicode value against the CJK Unified Ideographs block (0x4E00–0x9FA5), while `isChineseStr(String)` iterates through each character of a string using `toCharArray()` and returns `true` if any character qualifies. The logic relies on direct integer range comparisons on the primitive `char` type, with no external libraries or data sources involved. The implementation is straightforward and self-contained, suitable for text-processing tasks.

This visualization demonstrates the outcome of a string-mutation algorithm, showing whether two input words share all their characters. The code defines a function that checks if every letter in the second word appears in the first, returning a boolean result. The example specifically tests the words "hello" and "hey," which produces a false output because the letter "y" is missing from the first word. No external visualization libraries are used; instead, the display relies on the raw JavaScript logic and the console output from the gist. The data source is the hardcoded array passed to the function.

JS Bin

This example counts character frequency in a long string of text and outputs a sorted array of characters with their occurrence counts. The code uses JavaScript's `reduce` method to build a frequency object, then sorts the result in descending order using a custom `compareNumbers` function. The data source is a hardcoded string of lowercase letters and underscores. The final output is logged to the console via `console.log`, showing the sorted array in descending order by frequency.

Fork of hanzi

This fork of the hanzi example animates two Chinese character strokes using SVG and CSS. It shows light gray character shapes being progressively drawn with thick blue strokes, creating a handwriting effect. The animation uses CSS `@keyframes` with `stroke-dashoffset` transitions over two seconds, while SVG `clipPath` elements constrain the blue paths to the original character outlines. The code includes embedded SVG markup inside an HTML document and minor JavaScript that logs to the console.

charsethero : convert mixed utf-8 and iso-latin content to utf-8

This example demonstrates a command-line Perl script that converts mixed UTF-8 and ISO 8859-1 encoded text into a single UTF-8 stream. It reads from standard input, processes each line, and outputs the converted result. The core logic uses regular expressions to identify multi-byte UTF-8 sequences and single-byte Latin-1 characters, then applies the `encode_char_utf8` function to re-encode any non-UTF-8 bytes. The script also includes a `force_latin` function for reverse conversion, though the main pipeline calls `force_utf8`. The data source is standard input, making it a filter for text streams.

This example shows a utility function for determining whether two timestamp values fall on the same calendar day. It compares both the day-of-year and the year extracted from each timestamp, using the `Calendar` class from the Android or Java standard library. The function converts each `Long` timestamp into a `Calendar` instance via `getInstance()` and `timeInMillis`, then checks the `DAY_OF_YEAR` and `YEAR` fields. The code relies entirely on `Calendar` APIs and does not involve any visualization or external data source.

Normalizer

This example demonstrates a string normalization function that converts accented and special characters into plain ASCII equivalents. It builds a character mapping from two parallel strings, then processes each input character, replacing matches with their mapped counterparts and lowercasing the final result. The implementation relies on standard JavaScript string methods such as `charAt`, `hasOwnProperty`, `join`, and `toLowerCase`. The code is presented as a standalone JavaScript function, with no external libraries or data sources involved, showing the raw logic behind text sanitization in a compact form.

hanzi

This example visualizes two Chinese hanzi characters as animated blue strokes that draw themselves over a light gray grid. Each character is composed of two distinct path shapes, filled in light gray, with a blue stroke animating along a clipped path to simulate handwriting. The animation uses CSS `@keyframes` to control `stroke-dashoffset`, cycling through delays to sequence the strokes. The SVG is rendered inline in the HTML, scaled and reflected vertically, with a JavaScript console log included for debugging.

This example shows a string-processing algorithm that removes repeated characters from an input word. The code defines a function, `removeRepeatedChars`, which iterates through the original string and builds a new string by appending characters only when they do not already appear in the newly constructed result. It uses nested loops to compare each character against the current new word and tracks matches with a counter variable. The implementation relies on standard C++ string operations and does not use any external visualization libraries, instead presenting the logic directly as source code.
